Grails写的程序再次运行，出错HTTP Status 404 The requested resource () is not available

[cheery_an]

在Windows cmd下面：
grails create-app Contact
cd
grails create-domain-class Team
grails create-controller Team
grails run-app
初次这样，可以打开http://127.0.0.1:8080/Contact
当ctrl+C停止后，再次grails run-app
就出现错误：
HTTP Status 404 -
